Money well spent for the comfort of these socks.

Yes, I recommend this

I bought these socks because I had chilblains. Something I have never suffered from. After 7 days the chilblains had nearly gone. Today I am free of them thanks mainly to the socks

One of the socks can with large hole

No, I don't recommend this

One of the socks had a large hole on the ankle. A shame as the others seem fine. Not going to return a sock so two pairs out of three will have to do!

Excellent fit toasty warm socks

Yes, I recommend this

Bought for my son who says they are by far the warmest and most comfy of all the many thermal socks he has tried including well known thermal brands. A snug fit with ribbing in the right places keeping them in place. Well made toasty socks.

Lifesavers!

Yes, I recommend this

After several days working out in icy cold weather my feet were starting to suffer badly from chillblains. I ordered two packs of these wonderfully warm socks, which came within 48 hours, so super service there, and my feet have been toasty warm ever since. Like all M&S cloths I've ever purchased, they are excellent good value for money and I always know that the fit is perfect too.
